CROSS REFERENCES TO RELATED APPLICATIONS
[0001] The present invention contains subject matter related to Japanese Patent Application
JP 2004-300485, filed in the Japanese Patent Office on October 14, 2004, the entire
contents of which being incorporated herein by reference.
BACKGROUND OF THE INVENTION
Field of the Invention:
[0002] This invention relates to a portable terminal device such as a mobile phone unit
and to a reception method used by such a portable terminal, and in particular relates
to technology to display content on a portable terminal device.
Description of the Related Art:
[0003] The spread of mobile phone units and other portable terminals in recent years has
been accompanied by commercialization of mobile phone units which, in addition to
typical transmission and reception functions for conversation as well as e-mail transmission/reception
functions and Internet connection functions, also incorporate such varied functions
as television (hereafter "TV") reception functions, video game functions, and camera
functions. In the case of a unit incorporating TV reception functions, a tuner for
broadcast reception is built-in.
[0004] The various above-described functions are obtained through control and processing
based on application programs (hereafter "applications") stored in internal memory
of the mobile phone unit in advance. Applications have their own unique functions,
and may be used either independently or in concert with other applications. For example,
in addition to conversation processing in use as a telephone set, games may be displayed
onscreen, the unit may be used as a camera, music may be output, and various other
processing may be performed. For example, in the case of applications related to display,
an application may be read from memory corresponding to an instruction input by user
operation of a select/execute button or the like on the mobile phone unit; the application
is interpreted and executed by the CPU (Central Processing Unit) which controls the
various devices incorporated into the unit, causing content to be displayed in the
display portion of the unit.
[0005] When an application related to display is executed in a mobile phone unit, there
are cases in which two applications are executed simultaneously, and displays based
on the two applications are displayed simultaneously. As an example of simultaneous
displays based on two applications, for example, a Web browser and mailer may be started.
A Web browser is an application which connects to the Internet and causes the contents
of a web page or the like to be displayed. A Web browser may be used to specify a
particular URL (Uniform Resource Locator); or, by using a search engine or the like,
the contents of a object resource may be found through the Internet connection. Also,
a mailer is an application to send and receive e-mail. By using a mailer, a sender
and a receiver can specify each other's mail address to send and receive e-mail.
[0006] Upon simultaneously starting these two applications, and simultaneously causing the
contents of each to be displayed on a single screen, for example, the Web browser
can be used to enjoy the Internet connection while viewing e-mail displayed within
the mailer.
[0007] Patent Reference 1 discloses a mobile phone unit which uses two types of display
screens, which are a main display portion and a secondary display portion, and which
can simultaneously process a plurality of applications and cause application content
to be displayed on the different display screens.
[0008] Patent Reference 1: Published Japanese Patent Application No. 2003-204378 (FIG. 2)
SUMMARY OF THE INVENTION
[0009] However, when two applications are started simultaneously and made to display content,
settings related to the display of one application may be made based on processing
by the other application. For example, in a mobile phone unit incorporating a tuner
for TV broadcast reception, when an application to send and receive e-mail is started,
in the processing of the started applications, it may occur that e-mail is received
containing a list of recommended TV broadcast programs and link information to the
channels of the stations broadcasting the recommended programs.
[0010] When causing mail text and images of the received e-mail to be displayed by the mobile
phone unit, by performing an operation to select the link location to the channel
of a station broadcasting a recommended program in the displayed mail text, for example,
an application in the mobile phone unit to receive TV broadcasts may be started, and
the channel broadcasting from the specified station is received, with the received
images displayed in the display portion, and received audio output from a speaker.
[0011] Thus there are cases in which, based on an instruction in one application, processing
in another application may be linked and executed. However, depending on the current
location of the user in possession of the mobile phone unit, cases are conceivable
in which accommodation of the link in the e-mail is not possible.
[0012] Specifically, when for example there is link data in a received e-mail to the station
of a TV broadcast program broadcast in Hokkaido, if the user who has received the
mail is in a region other than Hokkaido, the link data is meaningless. Even if there
is automatic reception of a specific channel based on link data, there is a strong
possibility that the station broadcasting using the channel number is a different
station, and so the link function is not valid.
[0013] Here, a case is explained in which two applications, which are an e-mail function
and a TV broadcast reception function, operate in concert; but when two other applications
operate in concert also, a similar problem arises when execution of one of the applications
is limited by region.
[0014] This invention was devised in light of such circumstances, and is to provide the
resolution of problems in cases in which two applications operate in concert, with
one application used to execute another application having regional properties.
[0015] An embodiment of the present invention is a portable terminal device and reception
method thereof in which, when performing first reception processing to receive data
based on a first application program, second reception processing to receive data
based on a second application program, and application program execution processing
by the first and second application programs, and when specific data specifying processing
by the second application program is included in data received by the first reception
processing and the specific data has regional properties, the application program
execution processing is performed such that the current region in which the second
application program is executed is judged, and when the current region does not match
a region of processing specified by the specific data, content indicated by the specific
data is converted based on predetermined table data, and the processing of the second
application program is executed.
[0016] By this means, when data specified by processing of the first application program
has regional properties, and the current region does not match a region of processing
specified by the data, data conversion is performed, so that processing in which regional
properties match can be performed by the second application program.
[0017] According to the embodiment of the present invention, two application programs can
be operated in concert, and when processing having regional properties is specified
for one of the application programs based on the other application program, if the
current region does not match the regional properties, the contents specifying processing
having regional properties are converted; hence when executing processing having regional
properties, processing corresponding to the current location at that time can be performed,
and processing in accordance with the region becomes possible regardless of the current
location.
[0018] In this case, the first reception processing is processing to receive data via a
wireless telephone line; the second reception processing is processing to receive
broadcast content; and by performing processing to convert the reception channel or
reception frequency for the second reception processing, which is specified by data
received by the first reception processing, into another reception channel or reception
frequency, cases in which the channel or frequency of broadcast of a program differs
among regions can be accommodated.
[0019] Further, when performing conversion of the reception channel or reception frequency,
by making the table to perform conversions of reception channels or reception frequencies
based on electronic program guide information contained in broadcast data received
in the second reception processing, broadcast channels or frequencies for different
regions can be judged simply from the electronic program guide information.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] Hereinafter, an embodiment of the present invention is explained referring to the
attached drawings. This embodiment is an example of application to a portable terminal
device which, in addition to conversation send/receive functions, e-mail functions,
Internet connection functions and similar, is provided with functions for reception
of TV broadcasts. Here, an example is explained of application to a digital cellular-type
mobile phone unit as the portable terminal device.
[0022] First, an example is explained of the external shape of the mobile phone unit of
this example. FIG. 1 shows an example of the external shape of a mobile phone unit
100 of this example. The mobile phone unit 100 is configured to have an upper housing
5 and lower housing 7, connected by a hinge portion 6 as a support point and to be
capable of being folded. FIG. 1 shows the opened state. In FIG. 1, the inner-side
surfaces which are opposed when the telephone is folded are shown.
[0023] In the upper housing 5 are positioned a speaker 1 for audio output of the voice of
the remote communication partner during conversation and of call-received ringtones
and similar, as well as a display portion 2 which uses a liquid crystal display panel
or the like to display characters and numbers, symbols, icons, cursors, still images,
video, and similar. In the mobile phone unit 100 of this example, the display portion
2 is divided into two portions of arbitrary size, and it is possible to display different
content in the two display screens (multi-window display). In the lower housing 7
are provided a key operation portion 3 as input means, in which are placed dial keys
for the numbers 1, 2, ..., 9, 0 as well as the "#" and "*" symbols, various function
keys, a direction-specifying key to manipulate a cursor or the like, and an enter
key or the like to confirm operations, as well as a microphone 4 for audio input.
As the direction-specifying key and enter key, a jog-dial key may be used, which can
be operated rotationally and by pressing down.
[0024] In the upper part of the display portion 2 is a pictograph display area 20, which
displays various state icons for the mobile phone unit 100, and in this pictograph
display area 20 is reserved an area for display of a battery icon 21 indicating the
remaining amount of battery power and an antenna icon 22 indicating the radio wave
reception level. In this example, the display portion 2 of the mobile phone unit 100
is configured with two screens, above and below, to separately display images for
different applications. Specifically, as shown in FIG. 1, images for each of the different
applications can be displayed in the first display area 23 and second display area
25, resulting from the division into two portions, upper and lower, of the display
area of the display portion 2. Details of the display states in each of the display
areas 23 and 25 are explained below. In the lower part of the display portion 2 are
a left-operation icon 27 for left operation and a right-operation icon 28 for right
operation, which can be used to specify content, make onscreen movements, and similar.
[0025] In this example, a foldable-type mobile phone unit is used in explanations; but a
straight-type terminal, revolver-type terminal, or various other shape configurations
may be used.
[0026] Next, an example of the internal configuration of the mobile phone unit 100 is explained
referring to the block diagram of FIG. 2.
[0027] First, the reception system during voice conversation of the mobile phone unit 100
is explained. An antenna 11 is connected to a transmission/reception portion 12, and
receives signals transmitted by a predetermined communication method from an external
remote station, not shown in the figure, at the transmission/reception portion 12.
As the wireless communication method used by the transmission/reception portion 12
for transmission and reception, for example, CDMA (Code Division Multiple Access)
is used.
[0028] Reception signals received and demodulated by the transmission/reception portion
12 are supplied to a data processor 13, and a reception packet is extracted; from
the packet are retrieved the voice data, control data, and other necessary data. The
retrieved voice data is supplied to a voice processor 14, converted from digital data
into analog voice signals, subjected to amplification and other voice processing,
and supplied to the speaker 1, to output the voice of the remote communication partner.
[0029] The transmission system during voice conversation is explained below. Voice signals
supplied from the microphone 4 are converted into digital voice data in the voice
processor 14, the converted voice data is supplied to the data processor 13, and the
voice data is arranged in the transmission packet. Control data and other data are
also arranged within the transmission packet. The transmission packet generated in
the data processor 13 is supplied to the transmission/reception portion 12, and after
predetermined modulation processing has been performed, frequency-conversion into
transmission signals at a predetermined transmission frequency is performed, and the
frequency-converted transmission signals are transmitted wirelessly from the antenna
11. Those reception processing and transmission processing are executed under the
control of the CPU (Central Processing Unit) 17 of the terminal 100, and any necessary
information is displayed on the display portion 2. Programs required for control by
the CPU 17 are stored in a memory 18.
[0030] When performing data reception and data transmission in the mobile phone unit 100
of this example in order to send and receive e-mail, to access the Internet or the
like, the necessary data is extracted from received packets and the necessary data
is arranged into transmission packets in the data processor 13 under control by the
CPU 17. Processing of received data and processing of data for transmission are performed
through execution by the CPU 17 of applications with various functions, stored in
memory 18.
[0031] For example, when sending and receiving e-mail, e-mail data reception or transmission
is performed under control by the CPU 17, and display of received e-mail data by the
display portion 2, as well as input processing of e-mail for transmission by the key
operation portion 3, are performed through execution by the CPU 17 of an e-mail application
stored in memory 18. When accessing the Internet using a web browser also, a web browser
application stored in memory 18 is executed by the CPU 17, and downloaded images and
the like are displayed on the display portion 2. Control and other data are exchanged
between the CPU 17 and other portions via a system bus 19.
[0032] Next, functions to receive TV broadcasts, incorporated into the mobile phone unit
100 of this example, are explained. The terminal 100 is provided with a TV antenna
15, either externally or internally, as well as a TV tuner 16 connected to the TV
antenna 15. The TV tuner 16 of this example is configured as a TV tuner capable of
receiving ground-wave digital broadcast signals. Reception processing by the TV tuner
16 is executed under control of the CPU 17, and image signals obtained from the received
broadcast signals are displayed on the display portion 2, while audio signals obtained
from the received broadcast signals are output from the speaker 1 (or from an earphone,
not shown).
[0033] In the TV tuner 16, in addition to reception of the image signals and audio signals
which are the main content data of a TV broadcast, various other accompanying data
is also received. For example, EPG (Electronic Program Guide) data, used to display
program tables and similar, is also received. Processing to display a program table
or the like based on received EPG data is performed through execution by the CPU 17
of an application for TV broadcast reception, stored in memory 18. EPG data received
in a digital broadcast includes not only data for display of program tables for various
channels, but data relating to the stations for each channel. Data relating to a station
may be, for example, data relating to the system (broadcast network with which a station
is affiliated) to which the station belongs. In this example, when EPG data is received,
data relating to the systems to which stations included in EPG data belong is stored
as a table in memory 18. The state of storage in memory 18 is explained below.
[0034] The mobile phone unit 100 of this example is designed to be capable of simultaneous
execution of at least two among a plurality of applications, under control of the
CPU 17. That is, of the plurality of applications stored in memory 18, the CPU 17
can simultaneously execute at least two applications selected by key operations by
the user or by other means, and data can be displayed simultaneously based on processing
by each. For example, an e-mail application and a TV broadcast reception application
can be simultaneously processed, with received e-mail displayed in the display area
25 of the display portion 2 (FIG. 1), and received TV broadcast programs displayed
in the display area 23 of the display portion 2 (FIG. 1). Or, an application for connection
to the Internet and a TV broadcast reception application can be processed simultaneously,
with content displayed separately in the display areas 23 and 25.
[0035] Further, when simultaneously starting two applications, processing by one application
may be linked with processing by the other application. For example, when link data
specifying a program (content) broadcast by a specific station is contained in e-mail
received by an e-mail application, if the user performs an operation to select the
location displayed by the mail text corresponding to the link data, the CPU 17 starts
an application to receive TV broadcasts, causes the channel over which the program
is broadcast to be received by the TV tuner 16, and displays the images and outputs
the audio received. The CPU 17 judges the correspondence between the link data and
the actually received channel by referring to the received EPG data.
[0036] However, when broadcasts by a station broadcasting a program specified by link data
in a received e-mail cannot be received by the mobile phone unit 100 at its current
position, the reception channel specified by the link data is converted into another
channel reception of which is possible at the current position. At the time of this
conversion, the received EPG data is referenced to specify the conversion channel.
That is, based on the EPG data received by the TV tuner 16, the CPU 17 forms a list
(table) of stations which can be received in the region, and stores this list in memory
18. The data in this table is referenced, and when a station exists which broadcasts
the specified program (that is, when the region of broadcast of a program specified
by link data matches the region of a station which can be received at the current
position), this station is received. When the station broadcasting the specified program
does not exist among the stations in the table which can be received (that is, when
the region of broadcast of the program specified by the link data does not match the
regions of stations which can be received at the current position), the station most
suitable for reception is selected from the data in the table. When selecting the
station most suitable for reception, a station is selected for which systems match
among the station appended to the link data and a station indicated by data in the
table.
[0037] FIG. 4 shows an example of a case in which EPG data is received under control of
the CPU 17, and a list of stations which can be received in the region is formed as
a TV channel table. As indicated in FIG. 4, the EPG data includes the names of stations
which can be received in the region, the names of regions in which the stations can
be received, data relating to system stations with which a station is affiliated,
and data relating to the channel numbers of stations; this data is stored as a table.
When there is a change to this data, which is contained in EPG data received by the
TV tuner 16 (for example, when the position of the terminal 100 changes, and the stations
which can be received change), the data stored in the table is updated. The table
may be always stored in memory 18, or the table may be stored only while EPG data
received from TV broadcasts by the tuner 16 can be obtained, based on the received
data.
[0038] Next, an example of processing when two different applications in the mobile phone
unit 100 of this example are started simultaneously is explained. In this example,
an application to process e-mail and an application to receive a TV broadcast are
started simultaneously. Specifically, an application to cause display of received
e-mail is for example started, and with received mail text displayed in the second
display area 25 of the display portion 2, if the user operates the key operation portion
3 to select the location at which program link data in the mail text is displayed,
then processing by the application to receive TV broadcasts causes the TV tuner 16
to receive the channel on which the program is broadcast, and processing is performed
to display received images in the first display area 23 of the display portion 2 and
to output received audio.
[0039] FIG. 3 is a flowchart showing an example of processing when an application to process
e-mail and an application to receive TV broadcasts are started simultaneously. Processing
is explained according to the flowchart of FIG. 3 as follows. First, when e-mail is
received in processing by the application to receive e-mail, it is supposed that link
data to a specific program is received (step ST41). As the link data, for example,
the station transmitting the program or other transmitter information, and information
on the region of the broadcast is included. The transmitter information includes the
station, as well as data on the system to which the station belongs.
[0040] FIG. 5 shows an example of the configuration of broadcast program link data. The
link data is written in, for example, HTML (Hyper Text Markup Language) or another
markup language, and includes a place d1 to describe the program name, a place d2
to describe the assumed broadcast region, broadcast network information d3, and a
place d4 to describe the address at which the program is broadcast (that is, data
specifying the receiving station). In the description example of FIG. 5, the explanation
of the link data has been simplified, and the configuration differs from the actual
configuration.
[0041] Returning to the explanation of the flowchart in FIG. 3, suppose that such link data
was received, and the mail text containing the link data (content address before modification)
was displayed (step ST42). At this time, for example, the program name is displayed
as mail text. Then the CPU 17 judges whether there has been a user operation to select
the displayed program name (step ST43). If there has been no such user operation,
the application to receive TV broadcasts does not set (change) the reception channel,
and processing ends.
[0042] If in step ST43 there has been such a user operation, the CPU 17 causes the reception
channel of the tuner 16 to be set (changed) so as to receive the station contained
in the link data (step ST44). As the processing to set the reception channel, a judgment
is made as to whether the station is contained in a list of receivable stations indicated
by the EPG data received at the time, and if contained in the list, the station is
selected such that the channel for the relevant station is received. If on the other
hand, the station is not contained in the list, a judgment is made as to whether there
is a station with a system matching the system data of the station contained in the
link data, and if there is a matching station, the station with the matching system
is received.
[0043] Images of the broadcast program (content) of the station received in step ST44 are
then displayed in the first display area 23 of the display portion 2, while audio
is output from the speaker 1 (step ST45).
[0044] Here a specific example of operation is considered, and an example of a screen transition
due to content switching of the mobile phone unit 100 is explained, referring to FIGS.
6A and 6B. FIG. 6A is an example of the display on the screen before the transition;
FIG. 6B is an example of the screen display after switching.
[0045] In the example of FIGS. 6A and 6B, one of the applications among the two applications
started simultaneously is a digital TV viewing application, and as indicated in FIG.
6A, images from a digital TV broadcast program are displayed, as the content display
obtained from the application processing, in the first display area 23 of the display
portion 2. The other application is a mailer, and as indicated in FIG. 6A, received
e-mail text is displayed as the content display in the second display area 25 of the
display portion 2. The e-mail displays, for example, the title of "Today's program
information (Sapporo)" and titles of a TV program 26a (news) of XXX TV, a TV program
26b (documentary) of YYY TV, and a TV program 26c (variety) of ZZZ TV. FIG. 6A is
an example in which the station names are not displayed; but these may be displayed
together with the program titles. Here, when a program title is selected and confirmed
among the TV programs 26a to 26c, the channel on which the desired program is broadcast
is selected, and a link is set so as to display the TV program of the channel in the
first display area 23.
[0046] In this state, when, for example, the user performs an operation to select the title
of TV program 26b among the TV programs 26a to 26c displayed in the second display
area 25, the title of TV program 26b (documentary) highlighted is displayed, as shown
in FIG. 6B, and received images of the channel (the channel of YYY TV) on which the
TV program 26b is broadcast are displayed in the first display area 23. If the time
frame is that for display of the TV program 26b, the relevant documentary program
is displayed.
[0047] However, direct selection of the channel of the station specified by such link data
is possible when the broadcast region of the program indicated by the e-mail matches
the current region of the mobile phone unit 100. For example, suppose that the broadcast
region of the program indicated by the e-mail is Sapporo, and the current region of
the unit 100 is Tokyo. At this time, a TV channel table 101 has been formed based
on the EPG data received by the mobile phone unit 100; and by performing the reception
channel modification processing previously explained in the flowchart of FIG. 3, so
as to receive a station for which station data contained in this TV channel table
101 matches station data indicated by the link data for the selected TV program 26b,
any region can be accommodated.
[0048] Thus, there is the advantageous result that, even when the TV channel of the station
described in e-mail differs from the TV channels of stations in the region of the
user, a channel broadcasting the program recommended by the e-mail can be viewed,
without awareness of differences in region. In the example up to this point, an example
has been explained of using link data for switching processing of the TV broadcast
channel; however, a hard disk drive device or mass-storage memory may, for example,
be incorporated in the mobile phone unit, in a configuration enabling recording of
broadcast programs by the unit itself, and based on the program data, the reception
channel when reserving recording of the broadcast program may be performed by similar
processing, with channel changed as necessary based on link data.
[0049] In the above-described embodiment, an example was explained in which one of the applications
was an application for TV viewing, and the other application was a mailer; however,
other applications are possible, and connection to an objective TV program from a
TV program address described on a web site or the like is possible. For example, in
processing by an application for connection to the Internet, a web site displaying
a TV program table is accessed, the TV program table is displayed, and when a program
or channel is selected from the program table, the mobile phone unit may change the
reception channel according to the region in which the mobile phone unit is located.
[0050] In the above-described embodiment, judgment of whether a region to which data having
regional properties belongs matches the region of the unit was performed based on
EPG data received together with broadcast data; but this judgment may be made using
data other than EPG data. For example, a function to measure the position of the mobile
phone unit may be employed. Even when EPG data is used, EPG data downloaded from the
Internet or otherwise acquired by means other than a broadcast may also be used.
[0051] In the above-described embodiment, an example of using a mobile phone unit was explained;
but the invention is not limited thereto, and other portable terminal devices may
be used. For example, a PDA (Personal Digital Assistant) equipped with a TV tuner
and mail receiver functions may be used as the portable information terminal, and
similar processing is performed.
[0052] In the above-described embodiment, an example was explained of an application for
viewing TV broadcast programs as an application acquiring content with regional properties;
but application to other applications which acquire content with regional properties
is possible. For example, a receiver portion to receive radio broadcasts may be incorporated
into the terminal, and when another application is used to obtain link data to specify
a radio broadcast program, the reception frequency may be changed according to the
regions in which the radio station can be received.
